Wire Secondary Disconnect Assembly—AKR30/30H/50/50H/30L/30S
As mentioned above, the secondary disconnect blocks are available with all blocks installed. In this case, the
wires on the blocks will be routed through one side of the breaker and on the front. The wires on the front are
left loose for ease of landing the wires to the EntelliGuard ACB breaker secondary disconnects.
If the secondary disconnect blocks are installed at the customer site, the wires will not have been routed. The
wires should not be routed from the outside of the metal structure as it might interfere with the motion of the
kit during the racking into the compartment. Also, it should be ensured that the wires are securely fixed on
the inside metal frame of the Retrofilll kit using sticky pads and tie-wraps.
Verify that the the wire routing is not exerting pressure on bullets because this can bend the connection
points and effect biasing and contact pressure. By using tie-wraps and stickpads, wire routing can eliminate
sagging of the wire harness and pressure on secondary bullets.
Once the above mentioned steps are completed, landing of the wires to the points on the EntelliGuard ACB
secondaries can begin, based on the typical wiring diagrams found in
Figure 19 and Figure 20 .
